Excuses,Excuses: Self-Handicapping in an Australian Adolescent Sample   总被引:3,自引:0,他引:3  
The purpose of the present study was to examine gender differences in the self-handicapping tendencies of a sample of 337 Australian school attending adolescents, who were aged between 15 and 19 years. Self-handicapping, as measured by the shortened Self-Handicapping Scale, was examined in relation to self-esteem, performance attributions, coping strategies, and the potential behavioral self-handicaps of reduced study hours and inefficient study habits. Girls scored significantly higher on the Self-Handicapping Scale and endorsed using emotional and illness related excuses significantly more often than boys. High self-handicapping scores independently predicted lower study hours for boys, and were associated with less efficient study for girls. Coping and attributional predictors of self-handicapping were found to be rumination, luck attribution, and poor active coping strategies for boys, and ability attributions, behavioral disengagement, instrumental support, and poor active coping strategies for girls.  相似文献

Using data from Wave II of the National Longitudinal Study of Adolescent Health (Add Health; Bearman, P. S., Jones, J., and Udry, J. R. http://www.cpc.unc.edu/projects/addhealth/design.html, 1997), we conducted multivariate analyses to examine three indicators of psychosocial adjustment (school belonging, self-esteem, depressive symptoms) and their associations with sexual attraction status, sex, and urbanicity. In general, sexual minority adolescents reported lower psychological adjustment than adolescents endorsing other-sex attractions only, with sexual minority females at particular risk. Further, differential patterns of risk for sexual minority youth emerged across rural, urban, and suburban communities. We conclude by discussing implications of these findings for addressing the psychosocial needs of sexual minority adolescents.  相似文献

The role that parental authority patterns and social-cognitive identity styles may play in establishing identity commitments was investigated. The results indicated that family authority and identity style variables combined accounted for 50% of the variation in strength of identity commitment. As hypothesized, the relationship between parental authority and identity commitment was mediated by identity style. The findings are consistent with the view that family authority patterns may contribute to the way in which late adolescents negotiate the task of constructing a sense of identity. Alternative explanations of the findings are considered.  相似文献

Prior studies have found inconsistent relationships between measures of self-concept and adolescent alcohol use. The current study explored whether the link between various measures of self-concept and alcohol use depends on gender. In addition, earlier work suggested a focus on negative self-esteem (i.e., self-derogation) might be more useful in predicting alcohol use. Students (N = 1459) attending 22 middle and junior high schools in New York City completed surveys that included measures of efficacy, self-derogation, and alcohol use. Participants completed surveys at baseline, 1-year follow-up, and 2-year follow-up. Data collectors administered the questionnaire following a standardized protocol during a regular 40-min-class period. On the basis of a longitudinal structural equation model, lower efficacy was related to greater self-derogation a year later across gender. Increased self-derogation predicted higher alcohol use for girls but not boys. These findings are congruent with a literature highlighting the importance of negative thoughts about the self in drinking behavior for women but not men. The results suggest that the alcohol prevention approaches should include material to enhance girls' self-esteem.  相似文献

This study examined the nature and correlates of different patterns of perceived control in adolescents' relationships with their best friends. Participants included firstborn adolescents (M = 14.94 years), their younger siblings (M = 12.44 years) and both their mothers and fathers in 163 families as well as a best friend of each adolescent (M = 15 years). Data were collected from family members during home visits regarding adolescents' family relationships, friendships, and psychosocial adjustment; time use data were gathered during a series of 7 nightly phone interviews. Information was obtained from best friends during a brief phone interview. We developed a typology of 3 different patterns of perceived friendship control based on the combination of adolescents' and their best friends' ratings of relational control. Patterns of control in adolescents' friendships were associated with the distribution of control in both parents' marriages and adolescents' sibling relationships. Further analyses, designed to test developmental predictions, revealed connections between friendship control and other qualities of adolescents' friendships (i.e., intimacy, conflict, perspective-taking).  相似文献

The thaw of the Cold War ended the chess game between the superpowers and seemingly gave new momentum to the revival and spread of liberal democracy and its corollary, capitalism. Just as missionaries once offered Christianity to "save" colonised peoples, democracy has become the new gospel promising "salvation". Both donor and recipient countries appeal to democracy, hoping that it will reverse decades of misfortune. Donor nations and multilateral financial institutions preach democratic governance. "Born again democratic" national leaders in the South who are intent on clinging to power attend to their sermons. None appear to have a genuine faith in democracy. While some nations and NGOs do give altruistically, most use foreign aid as another means of pursuing their national interest. Democracy is an elastic concept. Indeed it seems, at least at this point, that the new gospel of democracy is but a convenient tool used by different players for they own selfish reasons.  相似文献

Virtually no one in the United States raised objections to the 1964 military takeover of the Brazilian civilian government. In the early 1970s, however, the Brazilian regime had become associated with torture and the arbitrary rule of law. By the end of that decade, compliance with human rights standards had developed into a yardstick for measuring U.S. foreign policy initiatives in Latin America. This paper argues that between 1969 and 1974, a small group of dedicated church activists, exiled Brazilians, and academics introduced the issue of human rights in Latin America into the U.S. national body politic. A network of concerned activists fashioned a systematic campaign to educate journalists, government officials, and the public about the abuses taking place under the generals' rule. Their activities helped isolate the military regime and laid the groundwork for a broader solidarity movement with Latin American popular struggles in the late 1970s and 1980s.  相似文献

Empathy, prosocial behavior, the number of friends, self-reported popularity, and various forms of interpersonal forgiveness were examined as predictors of peer victimization among 52 7th and 8th graders attending a private school. Popularity was the strongest individual predictor of teacher-reported victimization with high popularity associated with low victimization. Malestudents reported significantly higher rates of victimization than females, prompting the decision to examine correlates of self-reported victimization separately by gender. Interpersonal forgiveness scores were the strongest predictors of self-reported victimization; however, different forms of forgiveness were the greatest predictors of male and female self-reported victimization. Implications are discussed.  相似文献
